Ive always wondered how the motion of the earth would factor into instantaneous teleportation between to points on the same planet. Do you need to account for that to prevent yourself from being beamed underground or into space? Or does the fact that the source and destination are within the same inertial frame of reference make this one of those physics problems where the most complicated part turns out to be entirely irrelevant to the end-state?

Well according to the guy making the claim, it was divine intervention, so I guess God just did the math?

Was it Asimov or Heinlein who wrote about the kinetic-energy problem of teleporting around the globe? I think one proposal that the enormous losses accrued in some directions could be somehow banked against the enormous gains in reverse trips (reverse in energy flow, not in location - a 12-hour visit would mean both trips had the same "polarity").
